Overview
From a model code perspective, submittal of construction documentation, permitting, plan review, and field inspection may be required depending upon the specific details of renovating the floor above an unconditioned space (e.g., floor over a vented crawl space). Several different approaches can be taken to seal and insulate existing floors during a renovation project.

Buried Ducts within Ceiling Insulation of Vented Attics in all Climate Zones - Code Compliance Brief
Publication Date
Overview
The intent of this brief is to provide code-related information about buried ducts in vented attics to help ensure that the measure will be accepted as being in compliance with the code. Providing notes for code officials on how to plan review and conduct field inspections can help provide jurisdictional officials with information for acceptance. Providing the same information to all builders, designers, and others is expected to result in increased compliance and fewer innovations being questioned at the time of plan review and/or field inspection.
